llClaim.

rIhi's invention-relates to abrick cleaning' and shaping-machine,v the generalobject of the `invention being; to-provide'a wheel formed ofemery, Carborundum or thelike rotatably supported and arrangedl in a-casing with guide means forfholding'the bricksin proper position against therwheel and means for-rotating the wheel.

Another object"Of'theinvention is to provide blades on the wheel for blowing the dust from the casing and with meansKV for adjusting the wheeltotake upwear.

Thisinventiony also consists in certainother features'of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an elevational view of the apparatus with parts in section.

Figure 2 is an end view of the apparatus.

Figure 3 is a top plan View thereof.

Figure 4 is a section on the line 4-4 of Figure 1.

Figure 5 is a section on ure 4.

Figure 6 is a top plan View of the wheel supporting cylinder.

Figure 'l is a view of one of the fan blades.

In these views the letter F indicates a supporting frame which includes the pair of base members I, uprights longitudinal beams 3 and braces ll, A horizontal casing 5 is supported at the top of the frame by the uprights 6 connected with the beams 3. The top of the casing has an opening 'l therein and a spout 8 extends tangentially from the casing and has the hooks 9 thereon for hol-ding a bag or the like in position for receiving the dust and dirt from the casing as will be hereinafter described. A cylinder I extends upwardly through a hole II in the bottom of the casing and has the upwardly extending bolt I2 connected with its upper end, and a `disk or Wheel forming member I3 is fastened to the top of the cylinder by these bolts and their nuts I4. A ring-shaped member I of emery, Carborundum or the like is fastened by the disks I6 to the member I3, and blade forming members I'I are connected with the upper and lower faces of the member I3, these members I1 being preferably of the shape shown in Figure 'I and they the line 5-5 of Figform an air blast in the casing which will pass 2 through the spoutV or'chute 8 into av bag or'fthe like covering the. outer end of the chute and held thereon by the hooks 9. An angle bar I8 extends across the top of the casing and projects across a part of the opening 1, and an upright member of angle shape in cross section extends upwardly fromthe top of the casing as shown at I9,` these parts forming guiding means for holding a brick in position with a part thereof extendinginto thev casing to be engaged by the abrasive member I5. A pulley 2Q is connected with the lowerl part'of the cylinder It and has a plurality of V-shaped grooves 2l therein forr receiving V-shapedk belts 22 which pass over a similar pulley 23 on the shaft of a motor M which is supported on a platform 'Zt mounted on the frame. A bolt 25 threaded through a part of a bracket 26 on the platform is used to move the motor in a direction to tighten the belts. Thus the motor will drive the cylinder to rotate the member I3 and the abrasive member l5. A shaft 21 is supported in vertical position in a part of the frame and passes into the cylinder Ill and anti-friction means 28 is provided between the shaft and the cylinder. The lower end of the shaft 21 extends into a U-shaped member 29 depending from a part of the frame and having slots therein through which a pin Sli passes. The pin 30 also passes through the lower end of the shaft 21 so as to prevent rotary movement `of the shaft. A set screw 3l is threaded in a hole in the member 29 engaging the bottom of the shaft so that by adjusting the set screw the shaft can be raised and lowered to raise and lower the cylinder I0 and the parts carried thereby. A lock nut 32 is provided for holding the screw 3l in adjusted position.

A fence-lilre guard le is attached to the frame and covers the belts 22 and the pulley 23 to prevent injury to the operator from these parts and to prevent objects from falling on the belts or pulley to injure the same.

Thus it will be seen that when the motor is in operation the cylinder Ill will be rotated so as to impart rotary movement to the members I3 l5 so that the member l5 will clean mortar and the like from bricks held in contact with its upper face, and the dirt and foreign matter removed f rom the bricks will be blown from the casing by means of the blades Il into a sack supported on the spout 3. By turning the screw 3l the parts can be adjusted to take up wear. The device can be used for squaring up bricks and to give bricks any desired contour, such as rounding 3 the edges or beveling or shaping the brick to any desired form.

This apparatus will clean and shape bricks with practically no breakage and it greatly reduces the cost of salvaging old bricks for reuse.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

Having described the claimed as new is:

A brick cleaning and shaping machine com-*- prising a horizontally elongated supporting frame, a circular casing rigidly horizontally mounted upon and disposed above the top of said frame intermediate the ends of the latter, said casing having an angular opening in the top and adjacent a side thereof for insertion therethrough of bricks to be cleaned or shaped, and being provided with a tangential discharge spout which extends horizontally beyond one end of the frame, means for holding the mouth of a dust collection bag over the outlet end of said spout, coacting horizontal and vertical brick guides mounted on said casing at a corner of said opening, a vertical shaft mounted in the top of and projecting upwardly from said frame, a horizontal combined abrading ring and fan disk disposed within the housing and journalled on the upper portion oi invention, what is 5 extending over the belt gearing from the motor to the casing.
